Step 2: Locate deep pools Locate deep pools of water downstream from rapids. There will be a slow to moderate current there. Deep water means safety to fish, and as the current enters the pool, it brings food for the fish.

Step 3: Look below dams or waterfalls Explore the bases of dams or waterfalls. Falling water excavates a holding area for fish where they can wait for the current to bring them food.

Step 4: Look for reduced current Look for places where the stream's current is reduced -- at a point of land, an island, or at a sharp bend. Fish position themselves at the fronts and backs of eddies that form at such locations.

Step 5: Look for undercut areas Explore undercut areas along the banks of the stream. The undercut areas also attract fish.

FACT: The U.S. spends about $1 billion each year on stream restoration.
